fat foods, coffee, tea, milk, orange juice, etc. Salost DR (Risedronate Sodium delayed release) 35mg tablets should not be chewed,
cut, or crushed. Care should be taken not to break the outer coating which is designed to remain intact until the tablet reaches
the small intestine where the tablet coating dissolves and release the active ingredient.
If a dose is missed: Salost (Risedronate Sodium film coated) 5mg tablet: If an occasional dose is missed, Salost (Risedronate
Sodium film coated) 5mg tablet can be taken before breakfast, between meals, or in the evening according to the instructions
above.
Salost DR (Risedronate Sodium delayed release) 35mg tablet: Patients should be instructed that if a dose is missed, just take one
Salost DR (Risedronate Sodium delayed release) 35mg tablet on the morning after remember. Patients should then return to taking
one tablet once a week on the day the tablet is normally taken. Two tablets should not be taken on the same day.
Salost (Risedronate Sodium film coated) 150mg tablet: Patient should be instructed that if a dose is missed and the next month’s
schedule dose is more than 7 days away, then should take the missed tablet in the morning after the day it is remembered. Patients
should then return to taking one tablet once a month normally taken.
Salost (Risedronate Sodium film coated) 5mg, Salost DR (Risedronate Sodium delayed release) 35mg & Salost (Risedronate Sodium film
coated) 150mg tablets must be swallowed whole and not sucked or chewed. To aid delivery of the tablet to the stomach Salost
(Risedronate Sodium film coated) 5mg, Salost DR (Risedronate Sodium delayed release) 35mg & Salost (Risedronate Sodium film
coated) 150mg tablets are to be taken while in an upright position with a glass of plain water (120ml or more). Patients should
not lie down for 30 minutes after taking the tablet. Supplemental calcium and vitamin D should be considered if the dietary intake
is inadequate.
Elderly: No dosage adjustment is necessary since bioavailability, distribution and elimination were similar in elderly (60 years
of age or older) compared to younger subjects. This has also been shown in the very elderly, 75 years old and above postmenopausal
population.
Renal impairment: No dosage adjustment is required for those patients with mild to moderate renal impairment. The use of
Risedronate Sodium is contra-indicated in patients with severe renal impairment (Creatinine clearance lower than 30ml/min).
Contra-indications, warnings, etc
Contra-indications: Risedronate Sodium tablet is contra-indicated in patients
with known hypersensitivity to Risedronate Sodium and in patients with hypocalcaemia, severe renal impairment (creatinine
clearance lower than 30ml/min), during pregnancy and lactation.
Precautions: Foods, drinks (other than plain water) and medicinal products containing polyvalent cations (such as calcium,
magnesium, iron and aluminium) interfere with the absorption of bisphosphonates and should not be taken at the same time as
Risedronate Sodium. In order to achieve the intended efficacy, strict adherence to dosing recommendations is necessary. Efficacy
of bisphosphonates in the treatment of osteoporosis is related to the presence of low bone mineral density and/or prevalent
fracture. High age or clinical risk factors for fracture alone are not sufficient reasons to initiate treatment of osteoporosis
with a bisphosphonate. The evidence to support efficacy of bisphosphonates including Risedronate in the very elderly (>80 years)
is limited. Bisphosphonates have been associated with oesophagitis, gastritis, oesophageal ulcerations and gastroduodenal
ulcerations. Thus, caution should be used in patients who have a history of oesophageal disorders which delay oesophageal transit
or emptying (e.g. stricture or achalasia) or in patients who are unable to stay in the upright position for at least 30 minutes
after taking the tablet or if Risedronate is given to patients with active or recent oesophageal or upper gastrointestinal
problems. Prescribers should emphasize to patients the importance of paying attention to the dosing instructions and be alert to
any signs and symptoms of possible oesophageal reaction. The patients should be instructed to seek timely medical attention if
they develop symptoms of oesophageal irritation such as dysphagia, pain on swallowing, retrosternal pain or new/worsened
heartburn. Hypocalcaemia should be treated before starting Risedronate Sodium therapy. Other disturbances of bone and mineral
metabolism (i.e. parathyroid dysfunction, hypovitaminosis D) should be treated at the time of starting Risedronate Sodium therapy.
Osteonecrosis of the jaw, generally associated with tooth extraction and/or local infection (including osteomyelitis) has been
reported in patients with cancer receiving treatment regimens including primarily intravenously administered bisphophonates. Many
of these patients were also receiving chemotherapy and corticosteroids. Osteonecrosis of the jaw has also been reported in
patients with osteoporosis receiving oral bisphosphonates. A dental examination with appropriate preventive dentistry should be
considered prior to treatment with bisphosphonates in patients with concomitant risk factors (e.g. cancer, chemotherapy,
radiotherapy, corticosteroids, poor oral hygiene). While on treatment, these patients should avoid invasive dental procedures if
possible. For patients who develop osteonecrosis of the jaw while on bisphosphonate therapy, dental surgery may exacerbate the
condition. For patients requiring dental procedures, there are no data available to suggest whether discontinuation of
bisphosphonate treatment reduces the risk of osteonecrosis of the jaw. Clinical judgment of the treating physician should guide
the management plan of each patient based on individual benefit /risk assessment.
Use in pregnancy and lactation: There are no adequate data from the use of Risedronate Sodium in pregnant women. Studies in
animals have shown reproductive toxicity. The potential risk for humans is unknown. Studies in animal indicate that a small amount
of Risedronate Sodium pass into breast milk. Risedronate Sodium must not be used during pregnancy or by breast-feeding women.
Pediatric use: Safety and efficacy of Risedronate Sodium tablet have not been established in children and adolescents.
Side effects: Common: headache, constipation, dyspepsia, nausea, abdominal pain, diarrhoea, musculoskeletal pain. Uncommon:
gastritis, oesophagitis, dysphasia, duodenitis, oesophageal ulcer. Rare: glossitis, oesophageal stricture.
Drug interactions: No formal interaction studies have been performed, however no clinically relevant interactions with other
medicinal products were found during clinical trials. Among regular acetyl salicylic acid or NSAID users (3 or more days per week)
the incidence of upper gastrointestinal adverse events in Risedronate Sodium tablet treated patients was similar to that in
control patients. If considered appropriate Risedronate Sodium may be used concomitantly with oestrogen supplementation (for women
only). Concomitant ingestion of medications containing polyvalent cations (e.g. calcium, magnesium, iron and aluminium) will
interfere with the absorption of Risedronate Sodium. Risedronate Sodium is not systemically metabolized, does not induce
cytochrome P450 enzymes, and has low protein binding.
Overdose: No specific information is available on the treatment of overdose with Risedronate Sodium. Decreases in serum calcium
following substantial overdose may be expected. Signs and symptoms of hypocalcaemia may also occur in some of these patients. Milk
or antacids containing magnesium, calcium or aluminium should be given to bind Risedronate and reduce absorption of Risedronate
Sodium. In cases of substantial overdose, gastric lavage may be considered to remove unabsorbed Risedronate Sodium.
